Former boards

De Leidsche Flesch was founded in 1923. Since that time, there have been many different boards.

The board of De Leidsche Flesch was inactive at that time. The three seated members wanted to retire, but they could not find any successors. The people who tried to start the `dispuut' Tomas Jan Stieltjes were active but had less connection to physics and astronomy. Chris Sijtsma had been both treasurer at Tomas Jan Stieltjes and commissioner book sale at De Leidsche Flesch. If you became a member of Tomas Jan Stieltjes, you were automatically a member of De Leidsche Flesch and vice versa. Financially, all transactions of Tomas Jan Stieltjes passed the bank account of De Leidsche Flesch. There was no friction between the initiators of Tomas Jan Stieltjes. Fortunately, in the year that followed the astronomers Henk Latour and Wim Kokx were willing to take place in the board, giving Nelleke, Edwin and Chris Sijtsma support of other groups of De Leidsche Flesch. The less fortunate initiative of Tomas Jan Stieltjes has died a painless death.
